We ask what the audience looks like before asking how many there are. Fields are filled only where a source supports them. The handover is the point at which the criteria are verified, not assumed.
Date normalisation
Putting every date in one format and one timezone before any comparison runs.
Role inference limits
Saying which seniority judgements come from a stated title and which are guesses we declined to make.
Intake review
Reading an existing file and reporting what is wrong with it before any work is proposed.
There is no charge for finding out the answer is no.
